Tire tread



FIG. 1 is a front perspective view of a tire tread showing my new design, it being understood that the tread pattern repeats uniformly throughout the outer circumference and shoulder of the tire, the opposite side perspective view being identical thereto; and,

FIG. 2 is an enlarged fragmentary front elevation view of the tire tread thereof of FIG. 1.

The broken lines in the drawing indicate that the configuration of the three circumferential tread grooves forms no part of the claimed design. In the drawings, the dark stippled surface shading represents the recessed groove portions of the tire tread and shoulder areas. The broken line disclosure of the tire sidewall and inner bead is for illustrative purposes only and forms no part of the claimed design. 

The ornamental design for a tire tread, as shown and described.
